LOW POWER, SINGLE-SUPPLY, RAIL-TO-RAIL
OPERATIONAL AMPLIFIERS

MicroAmplifier Series
FEATURES
DESCRIPTION
The OPA344 and OPA345 series rail-to-rail CMOS
operational amplifiers are designed for precision, low-
power, miniature applications. The OPA344 is unity
gain stable, while the OPA345 is optimized for gains
greater than or equal to five, and has a gain-bandwidth
product of 3MHz.
● RAIL-TO-RAIL INPUT
● RAIL-TO-RAIL OUTPUT (within 1mV)
● LOW QUIESCENT CURRENT: 150µA typ
● MicroSIZE PACKAGES
SOT23-5
MSOP-8
TSSOP-14
The OPA344 and OPA345 are optimized to operate on
a single supply from 2.5V and up to 5.5V with an input
common-mode voltage range that extends 300mV
beyond the supplies. Quiescent current is only
250µA (max).
● GAIN-BANDWIDTH
OPA344: 1MHz, G ≥ 1
OPA345: 3MHz, G ≥ 5
Rail-to-rail input and output make them ideal for driving
sampling analog-to-digital converters. They are also well
suited for general purpose and audio applicaitons and
providing I/V conversion at the output of D/A converters.
Single, dual and quad versions have identical specs for
design flexibility.
● SLEW RATE
OPA344: 0.8V/µs
OPA345: 2V/µs
● THD + NOISE: 0.006%
A variety of packages are available. All are specified for
operation from –40ºC to 85ºC. A SPICE macromodel is
available for design analysis.
